The difference between the socket 100 represented in figure 1 and the socket 100 shown in figure 2 resides in its grounding means.

According to the embodiment represented in the Figure 1, these grounding means are constituted by a pin 2 that emerges from each cassette 110.

According to the embodiment represented in the Figure 2, the grounding means are constituted by two 2 'flexible tabs that emerge in the cabs 110 in the proximity of its cylindrical side wall.

Advantageously, the socket 100 represented in Figures 1 and 2 comprise, for each cassette 110, means of disconnection that facilitate the removal of a male plug current (not shown) of said cassette 110.

For each cassette 110, the disconnecting means of said socket 100 comprise a pusher plate 121 which is extends at the bottom 111 of the casket.

This pusher plate 121 constitutes a part of the bottom 111 of each cassette 110 and presents here a shape semicircular with, at its edge 121A extending according to a diameter, two notches 121B participating in the formation of said holes 112 (see figures 1, 2, 3, 4A and 4B).

Advantageously, as the figures show, and more in particular figure 3, the disconnecting means of the socket 100 of power socket associated with each socket 110 comprise a lever 120, formed by a single piece of which the plate pusher 121 constitutes an end, preferably made by molding of a plastic material, as well as pivot means 125, 103, 102 'of said lever 120 so that it can swing between two positions, namely a disconnection position in which said pusher plate 121 is raised (see figure 4B) and a position of connection in which said pusher plate 121 is lowered in the bottom 111 of each box 110 of socket 100 (see figure 4A).

More particularly, as Figure 3 shows, each lever 120 has a drive part 122 that is extends substantially parallel to the X axis of well 110 (see figure 1), in which an outer end 122A is available to the user, and an active part involves two arms 123, 124, one of the two arms, the outer arm 123, extends outside the cassette 110 and is connected to an end 122B of said part of drive 122, the other of the two arms, the inner arm 124, extends at least partially inside the cassette 110 and forming at its free end 124 said pusher plate 121.

The pivot means 125, 103, 102 'of the lever 120 are advantageously located in the vicinity of the confluence 127 between the two arms 123, 124 of said active part of said lever 120.

As Figure 3 shows, the part of actuation 122 of each lever 120 comprises, at its end outside 122A, a thrust plate 128.

According to the embodiment represented in the Figures 1 to 4B, this thrust plate 128 extends toward an edge outside of the trim plate 101 of the socket 100, and, according to the embodiment shown in figure 5, this plate of thrust 128 extends to the corresponding cassette 110.

In all cases, this push plate 128 allows a user to operate the lever 120 to pivot in the direction of descent or in the direction of elevation to lower or raise said corresponding pusher plate 121.

For this purpose, the trim plate 101 of the Socket 100 carries on the edge, next to each cassette 110, a elongate groove 105 leading to the edge 101A of said plate trim 101 and through which the part of drive 122 of the corresponding lever 120 and in which displaces said drive part 122 during pivoting of said lever 120 between its two connection positions and of disconnection

In figures 1 and 2, certain levers represented are in disconnected position, i.e. in position  lowering, and other levers 120 are in the connecting position, it is say in an elevated position, which corresponds to either an elevation of the pusher plate 121 or to a lowering of the latter.

To get to the bottom 111 of each box 110, advantageously, the drive part 122 and the outer arm 123 of the active part of the lever 120 form between them a acute angle?, preferably a right angle. In addition, the two arms 123, 124 of the active part of the lever 120 form between them an angle? which is an obtuse angle for example of the order of 120 degrees.

Finally, the end 124A of the inner arm 124 extends in the extension of the pusher plate 121 substantially parallel to the outer arm 123, thus forming a obtuse angle γ with said inner arm 124 of the same order than the angle?
